/AWS1/CL_DYNSCANOUTPUT

Represents the output of a Scan operation.

CONSTRUCTOR

IMPORTING

Optional arguments:

it_items TYPE /AWS1/CL_DYNATTRIBUTEVALUE=>TT_ITEMLIST TT_ITEMLIST

An array of item attributes that match the scan criteria. Each element in this array consists of an attribute name and the value for that attribute.

iv_count TYPE /AWS1/DYNINTEGER /AWS1/DYNINTEGER

The number of items in the response.

If you set ScanFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.

If you did not use a filter in the request, then Count is the same as ScannedCount.

iv_scannedcount TYPE /AWS1/DYNINTEGER /AWS1/DYNINTEGER

The number of items evaluated, before any ScanFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Scan operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.

If you did not use a filter in the request, then ScannedCount is the same as Count.

it_lastevaluatedkey TYPE /AWS1/CL_DYNATTRIBUTEVALUE=>TT_KEY TT_KEY

The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedKey is empty, then the "last page" of results has been processed and there is no more data to be retrieved.

If LastEvaluatedKey is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is empty.

io_consumedcapacity TYPE REF TO /AWS1/CL_DYNCONSUMEDCAPACITY /AWS1/CL_DYNCONSUMEDCAPACITY

The capacity units consumed by the Scan operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the ReturnConsumedCapacity parameter was specified. For more information, see Capacity unit consumption for read operations in the Amazon DynamoDB Developer Guide.

Queryable Attributes

Items

An array of item attributes that match the scan criteria. Each element in this array consists of an attribute name and the value for that attribute.

Accessible with the following methods

Method	Description
GET_ITEMS()	Getter for ITEMS, with configurable default
ASK_ITEMS()	Getter for ITEMS w/ exceptions if field has no value
HAS_ITEMS()	Determine if ITEMS has a value

Count

The number of items in the response.

If you set ScanFilter in the request, then Count is the number of items returned after the filter was applied, and ScannedCount is the number of matching items before the filter was applied.

If you did not use a filter in the request, then Count is the same as ScannedCount.

Accessible with the following methods

Method	Description
GET_COUNT()	Getter for COUNT

ScannedCount

The number of items evaluated, before any ScanFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Scan operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.

If you did not use a filter in the request, then ScannedCount is the same as Count.

Accessible with the following methods

Method	Description
GET_SCANNEDCOUNT()	Getter for SCANNEDCOUNT

LastEvaluatedKey

The primary key of the item where the operation stopped, inclusive of the previous result set. Use this value to start a new operation, excluding this value in the new request.

If LastEvaluatedKey is empty, then the "last page" of results has been processed and there is no more data to be retrieved.

If LastEvaluatedKey is not empty, it does not necessarily mean that there is more data in the result set. The only way to know when you have reached the end of the result set is when LastEvaluatedKey is empty.

Accessible with the following methods

Method	Description
GET_LASTEVALUATEDKEY()	Getter for LASTEVALUATEDKEY, with configurable default
ASK_LASTEVALUATEDKEY()	Getter for LASTEVALUATEDKEY w/ exceptions if field has no va
HAS_LASTEVALUATEDKEY()	Determine if LASTEVALUATEDKEY has a value

ConsumedCapacity

The capacity units consumed by the Scan operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the ReturnConsumedCapacity parameter was specified. For more information, see Capacity unit consumption for read operations in the Amazon DynamoDB Developer Guide.

Accessible with the following methods

Method	Description
GET_CONSUMEDCAPACITY()	Getter for CONSUMEDCAPACITY
